Abstract

Analyzed are thermally induced aberrations in optical beams propagating through solid-state laser media. Several geometrical configurations are considered: cylindrical rod, thin disk and slab. Predicted are thermally-induced optical effects in the temperature range of 77 - 770K. The analysis is based on an analytical solution to the problems of nonlinear heat transfer and material stressstrain field. Predictions are made for the temperature field, stress distribution, refractive index profile, ray trajectories, focal lengths, beam phases and aberrations. Most optimistic results are obtained for thin disk configuration in which the disk is attached to a heatsink and to a conducting cap on either facet.
